Several changes:
* Soft-Deprecate Buffer() constructors
* Add `Buffer.from()`, `Buffer.alloc()`, and `Buffer.allocUnsafe()`
* Add `--zero-fill-buffers` command line option
* Add byteOffset and length to `new Buffer(arrayBuffer)` constructor
* buffer.fill('') previously had no effect, now zero-fills
* Update the docs

// When calling .end(buffer) right away, this triggers a "hot path"
|
|
// optimization in http.js, to avoid an extra write call.
|
|
//
|
|
// However, the overhead of copying a large buffer is higher than
|
|
// the overhead of an extra write() call, so the hot path was not
|
|
// always as hot as it could be.

// Verify that our assumptions are valid.
